Study of Impact of Global Warming
Central Ground Water Board , under the Ministry of Jal Shakti, Department of Water Resources, River Development and Ganga Rejuvenation is periodically monitoring the ground water levels throughout the Country on a regional scale, through a network of monitoring wells.
The Dynamic Ground Water Resources of the country are also being periodically assessed jointly by CGWB and State Governments. As per the 2017 assessment, out of the total 6881 assessment units  in the country, 1186 units in 17 States/UTs have been categorized as ‘Over-exploited’ where the total Current Annual Ground Water Extraction is more than Annual Extractable Ground Water Resource.
Central Ground Water Board is implementing a nationwide programme of “National Aquifer Mapping and Management ” for mapping of aquifers , their characterization and development of aquifer management plans to facilitate sustainable development of ground water resources. So far about 11 lakhs sq.km have been covered. Aquifer maps and management plans have been shared with the respective State Government agencies. Public Interaction Programs are being organised at grass root level for disseminating the tenets of the Aquifer Management Plans for the benefit of the stakeholders.
The Research & Development Division, Project Planning Wing, Department of Water Resources, River Development and Ganga Rejuvenation wing of Central Water Commission  have awarded studies on impact of climate change on water resources to some of the premier educational institutes. The studies are being implemented under the supervision of Indian National Committee on Climate Change .
